Abstract:

Seedlings of barley (Hordeum vulgare L.), rye (Secal cereal L. ..) , wheat (Triticum aestivum L..) , and sudangrass (Sorghum sudanense (Piper) Stapf.) with resistance to Schizaphis graminum (Rondani) (B-biotype, originally ('collected on wheat) were tested for resistance to a greenbug (C-biotype, originally collected on sorghum) that ex- tensively damaged sorghums in 1968. 'Piper' sudangrass. 'Caribou Selection' rye and 'CI 9058/7 Bison' wheat were resistant to the B- but susceplible to the C-biotype. 'Dicktoo' barley and 'Insave F.A.' rye were the only cultivars resistant to both biotypes.
